There is, in fact, plenty of real debate among climate scientists. Opinions do get revised. For example: Science 17 November 2006: Vol. 314. no. 5802, p. 1064 QQQ News of the Week GLOBAL CLIMATE CHANGE: False Alarm: Atlantic Conveyor Belt Hasn't Slowed Down After All Richard A. Kerr A closer look at the Atlantic Ocean's currents has confirmed what many oceanographers suspected all along: There's no sign that the ocean's heat-laden "conveyor" is slowing. The lag reported late last year was a mere flicker in a system prone to natural slowdowns and speedups. Furthermore, researchers are finding that even if global warming were slowing the conveyor and reducing the supply of warmth to high latitudes, it would be decades before the change would be noticeable above the noise. The full realization of the Atlantic's capriciousness comes with the first continuous monitoring of the ocean's north-south flows. In March 2004, researchers of the Rapid Climate Change (RAPID) program moored 19 buoyant, instrument-laden cables along 26.5°N from West Africa to the Bahamas. A few months later, they steamed along the same latitude, lowering instruments periodically to take an instantaneous "snapshot" of north-south flows. While waiting for the moored array to produce long-term observations, physical oceanographer Harry Bryden and his team at the National Oceanography Centre in Southampton, U.K., compared the 2004 snapshot with four earlier instantaneous surveys dating back to 1957. They found a 30% decline in the northward flow of the conveyor (Science, 2 December 2005, p. 1403), sparking headlines warning of Europe's coming ice age. The first year of RAPID array observations has now been analyzed, and the next European ice age looks to be a ways off. At a RAPID conference late last month in Birmingham, U.K., Bryden reported on the first continuous gauging of conveyor flow. Variations up and down within 1 year are as large as the changes seen from one snapshot to the next during the past few decades, he found. "He observed a lot of variability," says oceanographer Martin Visbeck of the Leibniz Institute of Marine Science at the University of Kiel in Germany, who attended the meeting; so much variability that "more than 95% of the scientists at the workshop concluded that we have not seen any significant change of the Atlantic circulation to date," wrote Visbeck in a letter to the British newspaper the Guardian. Although the immediate threat has evaporated, a difficult challenge has taken its place. "Scientific honesty would require records for decades" in order to pick out a greenhouse-induced slowing, says physical oceanographer Carl Wunsch of the Massachusetts Institute of Technology in Cambridge. "How do you go about doing science when you need decades of record?" For their part, RAPID researchers will be asking for funding to extend array operations to a decade, says Bryden. Then some combination of government agencies would have to take on the burden of decades of watchful waiting.
